<br>
I have a host with 256G ram (and 32cores). I created 13 VMs (each<br>
requires 16G ram) first. Later I deleted all of them. I found that the<br>
kvm processes stay there for quite a long time (~10 minutes) and the<br>
memory was consumed by them. (so that my host started to use swap which<br>
cause it runs very slow). I wonder why deleting these VMs on host takes<br>
so long time. Does anyone know whether its because the low priority of<br>
deleting vm from openNebula scheduling perspective or there is some<br>
settings I need change?<br>
<br>
Thanks very much!<br>
